There is uncertainty with precipitation amounts overnight Monday into Tuesday. If snowfall amounts are on the high end of predictions, avalanche danger will be HIGH.

Most recent avalanche activity was reported as size 1-1.5 wind slabs in the alpine.

With heavy snowfall forecast for Monday night combined with strong winds, expect there to be an increase in natural avalanche activity in the alpine and treeline.

Please continue to post your reports and photos to the Mountain Information Network.

20-40 cm of new snow from the beginning of the week is being redistributed by primarily southwest winds.

A melt-freeze crust formed in mid-January is now buried up to 80-120 cm deep. In some areas, small facets are still found above the crust. This layer appears to be gaining strength but still remains a concern. The snow below this layer is well consolidated.

Snowpack depths are just below seasonal averages. Total amounts range from 150 to 300 cm at treeline, but decreases significantly below 1500 m.

Monday Night

Cloudy with snow, accumulation 15-30cm. Wind strong southwest. Treeline temperature -5 °C. Freezing level 1300 m.

Tuesday

Mainly cloudy with flurries, accumulation 3-5cm. Wind light to moderate northwest. Treeline temperature -7 °C. Freezing level 400 m.

Wednesday

Mainly cloudy. Wind light to moderate northeast. Treeline temperature -14 °C.

Thursday

Mix of sun and cloud. Wind moderate north wind. Treeline temperature -16 °C.

• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Storm slabs in motion may step down to deeper layers resulting in large avalanches.
